Specification of Letters Patent. Patented June 155, i914,

Application led March 14,' 1912. Serial No. 683,893.

This invention relates to improvements in.

blowers for boilers and the object of the invention is to provide a construction and arrangement especially adapted for effectively and expeditiously blowing all parts of Sterling and similar types of boilers.

A further object is to provide a construc-` tion particularly adapted to this type of boiler and which is such that the blower nozzles may be inserted through the usual clean-out openings in the wall of the boiler and may be retracted therefrom when not in use.

`Wth these and other ends in view the invention consists in the matter hereinafter' set fort-h and more particularly pointed out in the claims reference being had to the accompanying drawingsl 1n which,

YFigure' 1 `is a side elevation of a boiler setting with a blower Aembodying the invention in place thereon; Fig. 2v is a front elevationof the same; Fig. 3 a rear 'elevaticng' Fig. .4 is an enlarged detail of one of the lblower nozzles and adjacent parts showing the same partially in section; Fig. 5 is an elevation of one of the blower nozzles; Fig. 6 is a modified construction of nozzle showing the same in section; and Fig. 7 a detail similar to that of Fig. 4 showing a double arm nozzle support.

The invention is shown as applied to a Sterling boiler of a well known construction, but it is obvious that it may be applied to any boiler of this type.

As commonly,ieonstruittefl, afire arch. A, shown in dotted ylines in Fig. 1,'ertends over the fire chamber', andl in 'the liront. wall B of the furnaceabove said arch are provided with the usualv clean-out openings C. Extending across the upper end of the furnace are the three steam drums D and at the bottorn and near the rear ,twall of the settingi's the usual mud drum E, said mud drum and steam drums being connected by three inclinedy banks of tubes, F, Gr and H. Over .the bank F is baille l extending `from the mud drum. u .-vard tonear the forward steam drum and a similar baiiie J is located i adjacent to the rear 'side of the bank vGr .of tubes, extending downward from the middle steam drum. to near the mud drum. A.

short batiel extends laterally troni thel baffle ltoward the bank Gf ot tubes to cause the products of combustion to travel through said bank on their downward' course between the banks l? and G. In the side wall of the boiler setting are thel usual clean-out openings, an opening l( Abeing I located opposite the angle formed by the meeting of the battles l and l', openingsA L and L', located opposite the bank of tubes G, and the opening` M, opposite the bank H adjacent to the rear wall of the furnace, which wall is preferably provided with three clean-out Openings N arranged in a horizontal row adyacent to the lower ends` of the tubes of the bank H and near of the mudy drum.

Located adjacent to the side wall oi the furnace setting is a .vertical steam supply pipe l which may be connected to the boiler the top `Or any other source of steam or other gaseous fluid under pressure, and a branch supply pipe` 2 extends laterally from the pipe l and across the liront of the furnace over the openings C. A` branch supply pipe f 3 extends laterally from the `lower end of the pipe l across the side wall of the boiler setting to a vertical branch l and leading from the lower end of said branch is a supply pipe 5 extending across the rear wall of the boiler setting below the openings Y. i

The end of the pipes@ is turned downward i and supported by brackets 16 and 17 on the wall midway between the openings C. SaidV pipe is also' provided with a. shut-ofi' valve 6 and a swinging arm or branch 7 's con v nected to the lower end ofv this pipy by a packed pivot 8l and an elbowj 21 which is provided with an extension rod 2Q to engage 'the 'bearing 17 and forma pivotal support` for the arm 7, said support ermitting said arm to swing upon a vertice' axis from one pinto position` to to the other of said openings. The outer end of said arm is provided with a downwardly extendingconnection 9 to the lower end of which 'a pivot head is attached. Screwed into an opening in one side f the head 10 to swing about the axis thereof and receive steam therefrom, isa. nozzle pipe 11 providedy with a nozzle 12 at its free end, said head being turned to means of ya handle 13 secured in a'vsocket on the head, and thus the operator mayY swing the arm`7 into position before either of the openings C and then swing ,the nozzle pipe project through one of the openings. j

The nozzle 12 is formed with a single row .fof jet openings 14 arranged in a vertical .l branch 3 adjacent yto the opening K,

vertical pipe lwhich is secured to the face to said downturiiedvend plane in the sides and end of thenozzle to 'direct jets of steam upwardly` downwardly andv forwardly. These steam jetsstrike the bank F o f boiler' tubes and blow all of the accumulation of soot and products of combustion therefrom and at the saine timethe jets at the lower side of the nozzle strike the top of the arch A and` blow all accumulation therefrom. The nozzle pipe may be swung from side to side within the openings C to direct ythe. jetsagainst all of the tubes and blow the accumulation off-soot from every part'of the arch.

xtending upwardly from the supply of the side wall ofthe boiler setting by the brackets 16 and 17 in the same manner in which the fdownturned end of the pipe 2 is held iii place, this pipe'15 being equivalent like branch 7 aiid"'nozzle pipe 11 which is adapted to be projected through the opening K into the angle between the battles ,I and I. The nozzle 12 is preferably formed as shown in Fig. 6 with its jet openings 14 opening through the lower side and end of the nozzle only, to disteain downwardly into the angle between said baffles and blow out all accumulation of soot and productsof combustion which may have-lodged therein.

Extending laterally from the vertical branch supply pi e 4'is a short horizontal supply pipe 23 orsupplying steam to a bracket pipe 15 located adjacent to the opening L and provided with a swinging branch arm and nozzley pipe arranged similarly tothose adjacent to the opening K, and adapted to' be rejected through said -openng and blowt e lower ends of the bank of tubes Gr and the top of the' mud drum E.

' etween the openings L and M, a bracket pipe 15 extends upward from the. supply branch 3 and is supported in place in the same manner as the other bracket pipes by the bracket 16 adjacent to the supply branch swing thev pipe, by

arm 24 is i bow 2S to receive a short verticall connecting and provided with a upon this nozzleipipe,`

and the bracket 17 engaging the extension rod 22. A double-arm blower shown in detail in Figr7 is .carried by this bracket pipe and consists of a branch pipe or tubhlar arm l8 screwed into the ltting 21 and provided with a shut-ofi1 valve 19. jThe opposite end of said arm is provided with an upturned elbow 20 to which a parallel swinging arm or branch 24 having a down-turned elbow 25 is connected by a short vertical pipe 26 and. packed pivot 27, to swing in a horizontal plane parallel with the plane of movement of the arm 18. The opposite end of the provided with an upturned elpipe 29 pivot-ally attached packed pivot, 30 and upon the upper en said connecting pipe is a hollow head or casing 31 with itslongitudinalbore extending at right angles tothe axis of said pipe 29 toreceive a nozzle pipe 32, one end of which thereto bg a of is held to turn freely therein by a rib 33 on its end engaging a rib inthe casing, and a head 34 screwed into the end of the casing, which head forms a bearing for a rod 35 secured at its inner end to the end of the nozzle pipe and 36 on its outer end by means of which it may be turned to rotate the pipe 32. A. packing nut 37 in the end of the head around said nozzle pipe forms a tight joint to revent leakage of steam, and holes 38 in tie/pipe within the head afford communication between said nozzle pipe and the short ipe 29. To support the weight of the nozz e arms and take the strain from the arm 18, a bruce rod 39 is secured at one end of the elbow 20 on the outer end of said arm and it extends diagonally upward and is its opposite end to an ear on the cxtreme upper end of the extension rod or pipe 22 which engages-the bracket 17, said arm 18, rodl 39 and `bracket pipe 22 thus forming a triangular supporting frame for the lioiizontally swinging double-arm blower. This frame may be turned,to either side of its support to bring the arms in position in front of either of the openings L or M and by properly swinging said arms and nozzle pipe relatively, the pipe may be projected. through the openinfr and between any of the boilertubes exten infr across the opening. By means. of the handle 35 the nozzle pipe maybe turned on its axis to adjust the nozzle to the inclination of the tubes so that it may be projected betweenthem and blow longitudinally thereof or may be turned to direct its jets across the tubes. l f

The steam supply branch 5 'extending across the rear wall of the boiler setting is also provided ported in a like manner between two of the openings N 'and a double-arm construction the same as that provided for the openings with a bracket pipe 15 supprovided with a hand wheel'.

secured at L; M; is `attached thereto. "B n making said arms ofthe proper length, t e-- nozzle pipe may beprojected through any onhf the Vthree openings and inserted betwen the boiler-tubes to blow their lower ends-where theyventer the mud drum and to,t blow the accumulation of soot'from the top ofs'aid drum, The nozzle pipe may also be turned 4as describedto desired direction.

' the baffles' and the meetmg zle pipe may Ibe manipulated so that it will enter any of the spaces between the boiler tubes opposite each opening and then be `rejected far across the bank of tubes to low all parts thoroughly.,l The arrangement whereby the nozzle pipe may be turned on its longitudinal axis permits the turning of the nozzle so that it may be inserted within the narrow spaces between the boiler tubes regardless of the inclination or direction 'of said tubes and may be turned to di-l rectr4 the steain in any desired direction. Obviously. the double-arm construction'may be used for any'or all; of the openings in the boiler setting and any desirednumber of Vpivotally connected arms may be used.
